When it comes to raising a large breed puppy, nutrition is critical for healthy growth and joint development. In our evaluation, we looked for formulas with controlled calcium and phosphorus levels, high-quality protein from real meat or fish, and probiotics for digestive support. We compared several Diamond Naturals products against AAFCO standards and gathered owner feedback to identify the best options for large breed puppies.

We found that Diamond Naturals offers a range of recipes suitable for different life stages and coat needs, but not all are ideal for large breed puppies. Below we share our picks, buying factors, and tips to help you choose the best food for your growing pup.

Key Buying Factors
Large Breed Specific Formula
Look for AAFCO statement for growth of large breed puppies (over 70 lbs adult weight). These have controlled calcium and phosphorus to prevent skeletal issues.
Protein Source Quality
Real meat or fish as first ingredient provides essential amino acids. Avoid by-product meals and unnamed meat sources.
DHA and Omega Fatty Acids
DHA supports brain and vision development; omega-3 and omega-6 promote healthy skin and coat. Check levels from natural sources like fish oil.
Digestive Health Support
Probiotics and prebiotic fiber (like dried chicory root) aid digestion and immune function, especially important for sensitive puppy stomachs.
Kibble Size and Texture
Larger kibble encourages chewing and slows eating, reducing bloat risk. For small breeds, smaller kibble is easier to eat.
No Artificial Additives
Avoid artificial colors, flavors, and preservatives. Natural preservatives like mixed tocopherols (vitamin E) are preferred.
Care, Cost and Maintenance
Transitioning to New Food
Gradually mix new food with old over 7-10 days to avoid digestive upset. Start with 25% new, 75% old, then increase by 25% every few days.
Feeding Schedule and Portions
Large breed puppies do best with 3-4 meals per day. Follow weight-based feeding guidelines but adjust based on body condition. Avoid overfeeding to prevent rapid growth.
Monitoring Growth and Health
Track weight and body condition score monthly. Ideal growth is steady, not rapid. Consult your vet if you notice limping or joint issues.
When feeding our top pick, we recommend measuring portions using a kitchen scale for accuracy. Overfeeding even a quality food can lead to rapid growth and joint problems in large breed puppies.
